摘　　要：利用黑龙江省1961～2006年逐日降雪资料,分析了黑龙江省暴雪的时空分布特征,结论指出:黑龙江省年暴雪分布特点东多西少;暴雪量最大在10月份,暴雪日数最多在3月份;暴雪量和暴雪日数REOF分解的第一载荷向量空间分布基本一致,表明全省呈偏多(少)的一致型同位相分布;暴雪量和暴雪日数46 a无显著趋势变化,但存在明显的年际、年代际变化特征。Based on the daily snow data for the period from 1961 to 2006, temporal and spatial characteristics of snowstorm in Heilongjinag were investigated. The results indicate that the distribution of annual mean of snowstorm shows that snowstroms times in the eastern part of the province was more than that in the western part; The most snowstorm precipitation was in October, and the most snowstorm day number was in March; The first REOF eigenvector field of snowstorm day number was consistent woth that of snowstorm precipitation, showing consistent in-phase distribution of sonwstrom in Heilongjiang; No eminent trend of snowstorms in the past 46 years while its interannual and decadal variations were remarkable
